Legend Behind a Series

I'm working on a series that involves the ancient mythical creatures and how they are cursed as humans in modern day time. Each part of the story starts out with the "Legend" of how it came to be. Personally, I think the legend needs a little work, so I'm open to suggestions and such on how to fix it. Also, this legend is far to important to completely skip. It plays an important part on the climax/ending to the story.

The legend is as follows:

“There was once a great sorcerer who held a legendary power. This sorcerer was greatly admired by the people of the earth, the animals of nature often respected him and mother nature itself treated him with such care. Though the sorcerer had all these things, he wanted something more, he wanted the power of the mythical creatures, he wanted them and their immortality.
Thus the sorcerer devised a plan to trap the master creatures of the earth. In his plan he invited all the great creatures to a plentiful feast at the top of a great mountain, where only those with magical blood could reach. Believing the sorcerers intentions to be true the legendary creatures accepted his invitation and come to the feast. Little did they know that it was working into the sorcerers plans.
Soon however, the creatures learned of the sorcerers true intentions when they found that the food they were given had a special herb in them that would paralyze them. Unable to fight they were left helpless to the sorcerer who used the chance to achieve his true goal; to make the creatures belong to him and his descendents for all of time.
‘You foolish creatures” he had called to them. “Though you did not trust me, and some of you even hated me you came to my feast expecting me to give into you. But it is you who gave into me. Now you shall belong to me forever more! You shall be cursed to my blood and you shall not walk in your true forms! I will not allow you such glory! No! I shall shame you all and make you walk in the forms like mine! Ah, but do not think that is all! I will not allow you to love others, nor to enjoy the touch of others. For if you try to love someone other than me then you shall turn into your animal forms once more, and whoever you wished to love shall hate you!’
True to his word the sorcerer turned the great creatures into humans, and bound them to him by means of blood.”

However, for one of the stories there is also more to the legend. It is as follows:

“There was once a great sorcerer who held a legendary power. This sorcerer was greatly admired by the people of the earth, the animals of nature often respected him and mother nature itself treated him with such care. Though the sorcerer had all these things, he wanted something more, he wanted the power of the mythical creatures, he wanted them and their immortality.
Thus the sorcerer devised a plan to trap the master creatures of the earth. In his plan he invited all the great creatures to a plentiful feast at the top of a great mountain, where only those with magical blood could reach. Believing the sorcerers intentions to be true the legendary creatures accepted his invitation and come to the feast. Little did they know that it was working into the sorcerers plans.
Soon however, the creatures learned of the sorcerers true intentions when they found that the food they were given had a special herb in them that would paralyze them.

For if you try to love someone other than me then you shall turn into your animal forms once more, and whoever you wished to love shall hate you!’
True to his word the sorcerer turned the great creatures into humans, and bound them to him by means of blood.”

This is the curse of the Sorcerer family, it is a legend handed down in story books. However, this is not the full version of the legend, for there is a part that is written out of history by the family itself. That part? It is as follows:

“There was once a great sorcerer who held a legendary power. This sorcerer was greatly admired by the people of the earth, the animals of nature often respected him and mother nature itself treated him with such care. Though the sorcerer had all these things, he wanted something more, he wanted the power of the mythical creatures, he wanted them and their immortality.
Thus the sorcerer devised a plan to trap the master creatures of the earth. In his plan he invited all the great creatures to a plentiful feast at the top of a great mountain, where only those with magical blood could reach. Believing the sorcerers intentions to be true the legendary creatures accepted his invitation and come to the feast. There was one creature however who was unsure of the sorcerer and his attentions. That creature was the Pegasus, a beautiful and majestic creature that spent most of her time in the wind, listening to the whispers it brought her.
When the Pegasus heard of the sorcerer’s feast she tried convincing the other creatures that it didn’t settle right with her and that they would be wise to refuse. But the creatures would not listen, and accepted the sorcerer’s invitation. Angered by her fellow creatures the Pegasus refused to go to the feast, but still fearful she secretly followed them and watched the feast in the cover of the clouds. When she seen what the sorcerer had done to her friends she let out a cry and charged the sorcerer, but her efforts were for nothing.
Catching her the sorcerer grew angry at himself for missing the Pegasus. Growling in his anger he walked over to the Pegasus and grasped her by the horn, making sure to keep her from using her remaining powers against him.
‘Of all the creatures to refuse me, it had to be the one that protects the skies and virgins alike. You have made a dire mistake Pegasus for now your fate will be worse than those of your fellows. I will keep you by my side and give you the same fate as them, but you will know nothing but pain. I shall strip you of your horn, turning your beautiful coat into the flesh of a true monster. Your beauty will be nothing, all will flee from you, your fellow creatures will hate you, and blame you for their faults. There is another fate I have for you, but that is my own personal joy Pegasus. Do not think I will take mercy on you, for you will suffer worse than they shall! This is my promise to you!’
True to his word, the sorcerer stripped the Pegasus of her beauty and also turned her human.”
